SFECIFEUATION forming part `of Letters Patent No. 668,449, dated February 19, 1901.

Application filed November 8, 1900.

To @ZZ whom t may concern:

Be it k nown that LMIGHAEL MATHEW MAY,

-a citizen of the United States, and a resident of Rulo, in the county of Richardson and State of Nebraska, have invented a new and Im pro ved W'heclwrights Implement,of which the following is a full, clear, and exact de scription.

This invention relates to a peculiarly-con structed machine for holding vehicle-wheels during the application of the tire thereto and for permitting the wheels to be submerged in a tank immediately after the tire is placed in position, so as to cool the tire and shrink it on the felly. The machine is also useful for truing vehiclewheels to take the dish7 out of them, and, still further, it serves to prevent the dishing of wheels during the application of the tire, all as will fully appear hereinafter.

This speciiication is the disclosure of one form of the invention, while the claims de fine the actual scope thereof.

Reference is to be had to the accompanying drawings,forming a part of this specilication,

in which similar characters of reference indicate corresponding parts in both views.

Figure 1 is a side View of the apparatus, showing by dotted lines the various positions of the clamping devices; and Fig. 2 is a scctional view fully illustrating the operation of the parts.

a represents a tank, which is here shown to .be cylindrical in form and which forms the base of the apparatus. Mounted rigidly on the tank is a framing comprising two side bars b and a horizontal top bar bl, and arranged within the tank is a circular plate or bed c, adapted to carry the wheel, as shown 4o by full lines in Fig. 2, and formed with a centrally-located orifice c,through which the hub of the Wheel may be passed. vThis bed is carried by a U-shaped frame having side bars d and a top bar d'. The side bars d have guides d2 attached thereto, the guides running on the side bars b of the stationary frame, so as to guide the vertical movement of the bed-frame, permitting the frame to move up to the position indicated by dotted 5o lines in Fig. l or downward to the position shown by full lines in Fig. 2. The frame of Serial No. 35,837. (No model.)

the bed c is hung on the main frame by two links c, which are pivoted to the horizontal beam d' and straddle the beam b. The links e are connected at their upper end to a bellcrank lever c', the other arm of which is connected by a link c2 with a hand-lever e3, fulcrumed between projecting lugs b2 ofthe main frame. By throwing this lever c3 from the position shown in Fig. l to that shown in Fig. 6o 2 the bed-frame and the bed attached thereto may be moved downward to submerge the wheel in the water in the tank a, and by throwing the lever c3 back, shown in Fig. 1, the bed will be raised, and thus hold the wheel out of the water and in position. to be conveniently worked upon by the Wheelwright to place the tire on the wheel or to perform any other work that it is desired to do.

The bedframe carries devices for clamping 7o the Wheel on the bed, such devices moving freely with the frame and being independent of the tank and the main frame thereon. These devices comprise two clamping-levers f, which are fulcruined to the under side of the beam d. But one of these levers is shown in the drawings. They are, however, mere duplicatious of each other, and in operation they are essentially one. To these levers f is pivotally connected a short arm fl, in which 8o works a screw f2, and this screw carries a ball f3, fitting loosely in a socket formed in a clamp f4, which is adapted to engage the hub of the wheel, so as to clamp it down on the bed c, as shown. The leversfstraddle the beam d and also straddle one of the side bars b of the main frame, the levers projecting laterally beyond the said side bar and being connected by a link g with a hand-lever g', which is fulcrumed on two armsmgz, projecting rigidly from the adja- 9o cent side bar d of the bed-plate frame. By throwing the hand-lever g the clamping-1ever f may be moved to engage the clamp f4 with or disengage it from the hub, and also by adjusting the screw f2 in the arm f the 95 clamp may be caused to engage the hub of the wheel more or less firmly, as desired.

In using this device the wheelwright may place the wheel on the bed-plate, and it will thus serve to prevent the dishing of the Wheel, roo

and should the wheel be dished previous to its being placed in the apparatus this dish may be taken ont of it by pressing down the Wheel on the bedp1ate, as explained. When the tire is placed on the Wheel hot, by throwing up the lever es the wheel may be submerged in the Water in the tank and the, tire thus cooled and shrunk into place. The invention may also be used in various other ways, as will be apparent to skilled wheelwrights.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of a tank, a main framing erected thereon, a bed arranged in the tank, a bed-frame attached to the bed, a linkand-lever mechanism connected with the main framing and the bed-frame to sustain the bed on the main frame and to move the bed into and out of the tank, a clamp adapted to hold a Wheel on the bed, a clamping-lever fulcrumed on the bed-frame and connected with the clamp, and a link and lever carried on the bed-frame and connected with the clampinglever to operate the same.

2. In a wheelwrights implement, the com,

bination of a rigidly-sustained main frame, a bed, a bed-frame attached to the bed and arranged within the main frame, means connected with the two frames for raising and lowering the bed and bed-frame, and a clamping device mounted on the bed-frame an working with the bed.

3. A wheelwrights implement, having a tank, a m ain frame rigidly sustained thereon, a bed arranged within the tank, a hed-frame attached to the bed, means extending between the bed-frame and main frame for raising and lowering the bed-frame and bed, and a clamping device carried by the bed-frame and working with the bed, for the purpose specified.

In testimony whereof I have signed my name to this specication in the presence of two subscribing Witnesses.

MICHAEL MATHEW MAY.
